Steps to Get Bats Out of a Wall

One tranquil evening, you’re relaxing in your living room. Suddenly, you begin to hear squeaks from your wall. You pay closer attention and you observe movement. You think to yourself, “This must be a mouse”. But before you go back to your coach, you begin to hear flapping sounds. Yeah, this is no mouse. What you have are bats in your wall.

Aside from the constant noise disturbance they cause, bats in the wall will also leave their droppings which will contaminate the area. Moreover, they carry a series of health risks including rabies, and viruses related to severe acute respiratory syndromes (SARS). That’s why you need to get rid of them!

Why are bats inside your wall?

You might be curious as to why bats are in your wall. Here are some of the main reasons this may happen:

  1. Unresolved bat infestation: If you have bats residing in your attic and you fail to deal with it, then they may expand their reach to your walls, especially if it is in disrepair.
  2. There are outside cracks or holes in your house wider than half an inch that lead up to your walls.
  3. A bat colony expelled from a nearby location has temporarily relocated to your walls.

Steps to Get Them Out

Getting rid of bats from the wall is not an easy task for one major reason: You cannot easily see or access them. But before you proceed, make sure that you understand the legalities surrounding bat removal. For bat varieties that hibernate in winter, you have to wait until they leave in the fall. Furthermore, you cannot evict bats until their young are old enough to fly.

If you’ve confirmed that you can remove them, then by following these steps, you can get rid of them.

Identify & Seal Entry Holes

The first step is to carry out a thorough inspection to find out how these bats are getting into your home. Some bats species, like the little brown bat, can get in through holes as small as 3/8 of an inch. Common entry holes include broken windows and gaps near vents, or in the attic.

After you’ve identified the holes, seal all of them with caulk or steel wool to prevent them from getting back in. However, leave one hole (the primary hole) open.

Locate Their Position in Your Walls

The next task is to locate their position inside the walls of your home. This is usually daunting as they may be residing in multiple walls. For this task, your ears are your best guide. Ensure that everywhere is quiet, then listen attentively to scratching and flapping noises to pinpoint their location. As a tip, they usually reside in the wall close to their entryways.

Install an Exclusion Device

Now, it’s time to send them away. On the entryway that’s left open, install an exclusion device. This device ensures that bats can fly out but cannot fly back in. Eventually, all of the bats are going to leave.

Dealing with Stuck or Dead Bats

If a bat is stuck in your wall, then it would be unable to leave, and will eventually die. A dead bat gives off a noisome odor that will cause discomfort. To get rid of them, you may have to cut the wall. Here’s how to go about it:

  1. Identify the position of the stuck or dead bat. A stuck back will keep making noises. A dead bat, on the other hand, will give off a terrible odor. You need to use your nose to locate where the smell is most concentrated on the wall to pinpoint the location.
  2. Use a power tool to cut a neat, precise, and small hole.
  3. Remove the bat. Make sure you wear protective gear and gloves to prevent the risk of disease.
  4. Dispose of the carcass.


After removing bats, it’s important that their droppings are removed and the infected space is decontaminated. Because of the complexities associated with the removal of bats from the wall, it is best left to bat removal companies, as they have the expertise to effectively deal with the problem.
